eagle schematic define socket

Numerous Google searches seem to indicate that Eagle does not have any support for defining whether a part in a schematic is to be socketed, and defining the socket part number. Apparently this is not commonly done anyhow in most schematic capture programs, which seems like a shame. I got around this by simply adding my own attributes to the parts which had sockets, so that when the bill of materials gets generated those attributes show up in their own column. The attribute name that I chose to add where necessary was SOCKET_PN and also SOCKET_DIGIKEY_PN so that the ordering information for the socket would also be stored in the schematic. Naturally, I set "Visible" for these parameters to "off"
